You can't enforce "read only" behavior in an open file format. If

And if the file format is open, everybody can
change the file and so circumvent its logical "read-only" state.
You are not actually saying then that the whole idea of Document Rights
Management is impossible to implement in a Open Document Format, are you?
Nope, Mathias is saying read only can't be enforced with or without a
password in an open document format. The document content can always be
changed by altering the file directly rather than using the UI, since the
file's contents aren't in a proprietary binary format.
Hmmmm- well..
So what is being said is this maybe.
The concept of Document Rights Management, when the file format is Open,
is dependent on the producers maintaining control over distribution of
physical copies of the file. It is not manifest within the file itself.
